Error in running swing based sample application.

Hello Everyone,
I have downloaded the package for openjdk-6 and installed on my computer( linux ubuntu). Non GUI programs are running fine. But when I try the programs which have Swing GUI. I get the following error.
Exception in thread "main" java.lang.InternalError: No RenderingEngine module found

Please can someone point me in the right direction. This is really urgent. Thanks in advance.
